recls - Libraries Documentation

Version 1.6.1

Introduction

This is the documentation for the recls library. (Click here for release history.)

recls (http://recls.org/) is a C library (implemented in C & C++) that provides recursive file-system ¹ searching. It is described in my "Positive Integration" column, in C/C++ User's Journal (CUJ).

The purpose of the library is twofold. As well as providing an educational experience for the readers (and the author!) of the CUJ column, it is also intended to be a production-quality library, and it is my hope that it will find use throughout the development community. The license is very open, and allows use in any commercial or non-commercial organisation, without requiring provision of source, or runtime acknowledgements.

Language Mappings

In addition to the recls C API, the recls library includes the following language mappings:

recls.c++ C++: A set of simple classes that provide a user-friendly interface over the recls C API
recls/C# C#: A .NET mapping written in C#.
recls/COM COM: A mapping to a COM Collection, written in ATL.
recls/D D: A mapping to D.
recls/Java Java: A mapping to Java, demonstrating JNI (Java Native Interface).
recls/Python Python: A mapping to Python, demonstrating Python extensions.
recls/Ruby Ruby: A mapping to Ruby, demonstrating Ruby extensions.
recls.stl STL: A mapping of the recls C API to C++, providing STL-like sequences representing matching file ranges, and directory sub-components.

Several other mappings will be provided, as the library evolves through the column:

Ch
Heron
Managed C++: A .NET mapping written in Managed C++
Perl
Python
Tcl

Installation

At the moment, the libraries are provided in source (+ project) form only; there are no binaries. This means that you are required to build the libraries yourself. Since the project is primarily educational, this shouldn't present an issue (I hope).

Building the libraries requires that you have version 1.6.5 or later of the STLSoft libraries, and that you've defined the enviroment variable STLSOFT_INCLUDE to refer to the STLSoft directory.

Once other language mappings, that rely on dynamic libraries (such as the .NET ones), then it is possible that binary versions will be made available.

Compilers

At the current time, the supported compilers are:

Borland C/C++ (versions 5.5.1, 5.6 & 5.6.4)
Comeau C++, (version 4.3.0.1 & 4.3.3)
Digital Mars C/C++ (versions 8.35 and above)
GNU C/C++ (versions 3.2 and above)
Intel C/C++ (versions 6.0, 7.0, 7.1 & 8.0)
Metrowerks Code Warrior (versions 7.0, 8.0 & 9.0)
Microsoft Visual C/C++ (versions 5.0, 6.0, 7.0, 7.1 & 8.0)

Note that for version 1.0.1, makefiles are provided for Borland C++, CodeWarrior, Digital Mars, GCC and Visual C++ only.

Acknowledgements

Many thanks are due to Chuck Allison, Joe Casad & Jon Erickson, and C/C++ User's Journal & CMP publishing, without whose faith in my ability to steward the "Positive Integration" column, the recls project wouldn't exist.

Thanks are also due to the following, who've lent support in one way or another:

David Hackson of Intel
Garth Lancaster
Greg Peet (gregpeet.com)
Herb Sutter (www.gotw.ca)
Jeff Tieszen of Metrowerks
Walter Bright of Digital Mars
Yukihiro Matsumoto of Ruby
Microsoft
Borland

Best regards, and good coding
